For some reason my games been lagging the most when I get close to my cluster of gyroids. I have about 15 of them all in the same area and as soon as I get even close my game lags really badly. If I put 5 or 6 in my pockets it'll stop lagging, so I guess I'll have to have more than one spot for gyroids.
I've noticed more lag on my island than before the update. In the spots where it lags I do have a ton of flowers on screen, so that's what's causing the problem for me, I just haven't done anything about it (yet, at least).
I've noticed a little bit more lag but I started filling my island out a lot more after the update so I'm not sure what to attribute it to. I've also noticed it a bit more when my Switch is docked. It's not really that bad for me but it does get a lot worse if I'm looking at dream towns. Especially if they're cottagecore.
i haven't noticed a lot more lag or anything but man does it feel like the game takes forever to load now. was somehow hoping for them to make the game load faster but instead it's now a lot worse
